Why Is the Solar System Flat?

As soon as our solar system was made from a spinning cloud of dust and gas, it came about to form in such a way that all planets assemble on a single plane.

As soon as our solar system was made from a spinning cloud of dust and gas, it came about to form in such a way that all planets assemble on a single plane. But through all of 3D space to select from, why did it turn out plane or flat?

Observing that plenty of other arrangements in the Universe are flat, too, this Minute Physics video attempts to describe why. The answer is grounded on the way particles in huge dust and gas clouds travel and strike, as well as a coincidence of the fact that we occupy a 3D Universe. But at that fact, watch the video, since it clarifies it way, way better than I ever can. [MinutePhysics]

Liquid Water Exists on Jupiter's Moon Europa, NASA Confirms

Image
Huge plumes of water have been spurting out of Europa, one of Jupiter’s moons – and it might be the best place in our solar system to find aliens. The shock finding comes from a new look at old data, and has led scientists to confirm that the moon is a leading candidate in our search for alien life. Europa has long been seen as a possible candidate to have extraterrestrial life in our own solar system. But getting to it seemed almost impossible: the planet is thought to be covered in a thick crust of ice that would stop us from reaching the ocean beneath. The new discovery makes it much easier to actually find: the plume means that scientists can “taste” the water on the moon, helping them understand what might be found there. The plume was discovered when scientists realised that a bend in Europa’s magnetic field observed by NASA’s Galileo spacecraft during a 1997 flyby appeared to have been caused by a geyser gushing through its frozen crust from a subsurface ocean, researchers who r...

Supermassive Black Holes or Their Galaxies? Which Came First

There’s a supermassive black hole at the center of almost every galaxy in the Universe. How did they get there? What’s the relationship between these monster black holes and the galaxies that surround them? Every time astronomers look farther out in the Universe, they discover new mysteries. These mysteries require all new tools and techniques to understand. These mysteries lead to more mysteries. What I’m saying is that it’s mystery turtles all the way down. One of the most fascinating is the discovery of quasars, understanding what they are, and the unveiling of an even deeper mystery, where do they come from? As always, I’m getting ahead of myself, so first, let’s go back and talk about the discovery of quasars. Back in the 1950s, astronomers scanned the skies using radio telescopes, and found a class of bizarre objects in the distant Universe. They were very bright, and incredibly far away; hundreds of millions or even billion of light-years away. The first ones were discovered in ...

This Awesome Periodic Table Shows Where Do All The Elements Come From

Image
Here’s something to think about: the  average adult human  is made up of 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms, and most of them are hydrogen - the  most common element in the Universe , produced by the Big Bang 13.8 billion years ago. The rest of those atoms were forged by ancient stars merging and exploding billions of years after the formation of the Universe, and a tiny amount can be attributed to cosmic rays - high-energy radiation that mostly originates from somewhere outside the Solar System. As astronomer Carl Sagan once said in an episode of  Cosmos : “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” To give you a better idea of where the ingredients for every living human came from, Jennifer A. Johnson, an astronomer at the Ohio State University, put together this new periodic table that breaks down all the elements according to ...
